PRINTING MACHINE,

Application filed July 9, 1926, Serial No. 121,437, and in Great BritainJuly 17, 1925.

This invention is for improvements in or relating to cigarette makingmachinery, and more particularly to a printing device for use withcigarette making machines of the continuous rod type, and has for itsobject the provision of a printing device which is simple in itsconstruction and efiicient in its operation.

In cigarette making machinery the pr nting device usually employed,comprises a transfer roller rotatable by a ratchet mechanism and camoperated in such a manner as to periodically moveout of an ink duct,

into contact with the surface of a furnishing roller. The furnishingroller is adapted to reciprocate in the direction of its longitudinalaxis and engage with three or more transfer rollers. The transfer rollerwhich is the last to receive its supply of ink from the furnishingroller is adapted to engage with the embossed portion of a printingroller and supply the same with a quantity of ink.

' The printing device referred to above occupies a considerable spaceupon a cigarette making machine, and it is an object of the presentinvention to reduce space occupied by such printing apparatus.

The present invention consists of a printing device for use upon acigarette making machine of the continuous rod type, which comprises, anintaglio engraved roller ada ted to receive ink from a'duct, means orexample a doctor blade) adapted to remove excess of ink from the surfaceof said roller, and means adapted to bear upon saidengraved roller andtransfer, at regular spaced intervals; an impression from said engravedroller to a travelling web of cigarette paper.

Further the resent invention consists of the use on a cigarette makingmachine of the continuous rod type of an intaglio en-' graved roller forprinting at regular spaced intervals, upon a travelling web of cigarettepaper. 1

It has hitherto been proposed to emplo an intaglio engraved roller forprinting upon a travelling web of material but in such cases thefinished web has been substantially covered with printed matterand'consequently slight defects produced upon the un-printed portions ofthe web are scarcely noticeable.

The invention is more particularly described with reference to theaccompanying drawings, in which I Fig. 1 illustrates in elevation, adouble colour printing device, constructed according to the presentinvention.

Fig. 2 illustrates a web which has been printed upon by the deviceillustrated in 1, and

Fig. 3 is a modified construction of the printing elements illustratedin Fig. 1.

Referring to the drawings, a moving web 1 of cigarette paper is passedbetween an intaglio engraved printing roller 2 and a pressure roller 8.The pressure roller 3 is provided with a boss or raised portion 4 equalin length to the impression it is proposed to reproduce upon the paper.With the above arrangement, the contact of the web 1 with the printingroller 2 takes place only during the time which the boss or raisedportion 4 bears upon the web 1, the web at any other time being out ofcontact with the roller 2. a

The roller 2 is adapted to receive ink from a duct 5, in which ismounted a furnishing roller 6, pivotally mounted in the duct 5 andadapted to be pressed into en gagement with the roller 2 by means of thespring 7. Adapted to engage with the surface of the roller 2 is a doctorblade 8 which is reciprocated in the direction of the longitudinal axisof the roller 2. The rotation of the pressure roller 3 is timed sothatFig. 1 are similarly constructed, and the rotation of the respectivepressure rollers of the printing device is timed so that the printing onthe web, is spaced apart by the desired. distance in the mannerillustrated in Fig. 2.

Referring to Fig. 3, the pressure roller 3 is carried upon an arm 9which is pivotally mounted at one end upon a pin 10, and is adapted toengage at its free end with a spring 11 which is arranged to hold theroller 3 in engagement with the surface of the printing roller 2.Mounted on the arm 9 is a roller 12 which is adaptedto enga e with a cam13, mounted on onerface of t e printing roller 2. The profiler of thecam 13 is designed in such a manner that the pressure roller 3 is movedaway from the printing roller 2 immediately the printing operation uponthe web 1 has been effected.

What I claim as my invention and desire to secure by Letters Patent isIn a cigarette making machine of the continuous rod type in which a webof cigarette paper is drawn continuously from a reel, an intaglioengraved printing roller disposed between the reel and the said drawingmeans, a furnishing roller rotatably mounted in an ink duct so as toyieldingly engage -with said printing roller and supply ink thereto, apivotally mounted spring controlled doetor blade arranged to engage withsaid printing roller, a pressure roller mounted above said printingroller and operable automatically to press periodically a traveling webof paper into engagement with the engraved portion of the said printingroller and permit the web to disengage from the non-engraved portion ofsaid roller.

In testimony whereof I hereunto affix my signature.
